The droop nose is a feature fitted to a small number of aircraft types so the nose of the aircraft can be lowered during takeoff and landing to improve the pilot's view of the ground below. This feature is used with a very-low aspect ratio wing such as a delta wing .
Droop flaps function with other high-lift devices on an aircraft to increase the camber of the wing and reduce the stalling speed.On the Airbus A380, the first stage of lift device selection deploys the droop flaps (called droop noses by Airbus) and leading-edge slats located further out on the wing; with the main flaps starting to extend when the second stage is selected.
Beaked nose (slightly bent downward at tip) that is slightly off center and contains a deviated septum [2] Malocclusion associated with dental abnormalities including enamel hypoplasia (thin enamel due to incomplete formation), hyperdontia (extra teeth), and peg teeth (small, abnormally shaped teeth) [6] Cleft palate with high arch [6]
The use of high-lift devices on the leading edge of the wing lowered the landing angles to the point where the "drooping nose" was not required, and a more conventional rounded design was used. Compared to the other designs, the rounded nose profile and more cylindrical cross-section gave the NAC-60 a decidedly more conventional look than the ...
Empty nose syndrome (ENS) is a clinical syndrome, the hallmark symptom of which is a sensation of suffocation despite a clear airway. This syndrome is often referred to as a form of secondary atrophic rhinitis .
A second repair can sometimes be required; causes are recurrence of cancer, new cancer or new trauma. A second flap can be harvested from the contralateral forehead after a prior vertical flap. [1] If an oblique or angled flap was used during the first surgery, the second repair becomes more difficult.
The second stage, if needed, involves reconstruction of the orbital floor. While some clinics perform the two stages simultaneously, [13] [14] [15] most authorities recommend waiting a minimum of 6 or as many as 18 months, as spontaneous remodeling of the orbital floor after the sinus repair will occur in many if not most cases.
Long face syndrome, also referred to as skeletal open bite, [1] is a relatively common condition characterised by excessive vertical facial development. [2] Its causes may be either genetic or environmental.
